Dr.Gustilo is exactly what we all look for in a PCP. She is knowledgeable , honest , kind, compassionate, attentive and takes her Oath to be a doctor very seriously. She has helped me on every level as a human being and her faith and belief in me, has given me the courage and support to continue to push myself through horrible chronic pain, depression, anxiety and not loose faith in our medical system. Thank you for doing the lords work as an angel. [redacted]

This was my first visit with this provider, and I couldn't be happier with the experience. I switched from a different practice and felt so much more at ease. I actually felt like I was being listened to and not just glossed over.

I appreciate that she listened to me and didn't push me into anything I was uncomfortable about. I am very nervous when visiting a doctor and she and the nurse were very patient and understanding. They made my visit a great experience for me. I already told my daughter that she should also go to see Doctor Gustilo.

Dr. Gustilo not only cares about your physical health but also your mental health. She remembers that my husband passed away last April and she knows that the two go hand in hand. She listens well and asks important questions before diagnosis!

I find that Mary Gustilo's office from the start to the finish is incredibly kind, professional, and thoughtful. I have been going to Dr. Gustilo for probably five years, and I think she's expedient. I think she takes time to explain things, and she definitely has tremendous compassion for people that need her help. So I very much enjoy her as my primary care physician. Thank you.
